IGNITING DEv'IcE.

Specification of Lettersatent.

Patented Oct. 1, 1912.

`Application led November 28, 1911. Serial No. 663,654.

To ail 'whom it may concern.'

` Beit known that I, ELIs Gr. CARLSON, a subject of the King of Sweden, residing at Trenton, in the county of Mercer and State 5 of` New Jersey, have invented certain new and useful Improvements in Igniting Devices, of which the following is a specification.

My invention has relation to that class of' igniting devices for gas jets -or the like j wherein a spark or sparks are produced by striking small particlesfrom one substance Y during its abrasion by anothersubstance. Such devices operate upon the principle of the flint and steel inasmuch as the spark or sparks are produced by the removal from a material similar in its nature to flint, of

minute particles which are heated to nearV incandesoence by their sudden removal from the flint like substance when the steel like member abrades lor rubs upon the point or pencil lof the material.

The principal object of my present inven-l tion is to provide a simple and efficient igis a vlongitudinal sectional vview thereof,

`with the operating -lever and parts partly retracted. [Fig 3, is a view similar to Fig.`

- 2, but illustrating the normal position of parts after operation. Fig. 4, is an under? neath plan view of the l ignition device.l Fig. 5, is a cross-sectional `view taken on 4:5 line 5 5. of Fig. l, andFig. 6, is a longitudinal sectional view, enlarged, taken on the line 6-'6 of Fig. 3. l j

' Referring to' the drawings, 7 :represents .the handle for the device which,' as shown, is preferably made of sheet inetal stamped and bent into two substantially-parallel and at..-members between which the" operating members ofthe device are inclosed. The 'handle 7 has at its forward end al` tubular projection or nippleA 8 [which is screw?- threaded asat 9,31pon exterior and upon lholds the trigger arm 12 .in a 'substantially lis as follows Sliding in the nipple 8` is a i this projectin or nipple 8, a screw-threaded cap 10-is adapted to be advanced or retracted andIJ ca n be entirely removed therefron` as occasion requires. The handle 7.

.has its forward portion cut away at the bottom as at 11 and has intermediate` of its ends a bolt or rivet 12 forming the fulcrum for a lever arm 13 which traverses the handle vtransversely and projects beyond the 55 upper edge of the handle 7 in the form of a trigger '14. This trigger 14 works in aslot `15 eut longitudinally inthe upper edge of the handle 7. `rit the forward endy of the handle 7 adjacent to the nipple 8 and be- 'tween the sides of the handle is `pivoted a sector like disk 16 having ratchet teeth 17 vonl thatportion of its periphery adjacent to the opening in the nipple 8 and having a plain cam surface 1S/on the other or rear 75 portion of its periphery. This cam surface. 18 has a notch 19 arranged 'to receive the angular or tooth shapedmd 20 of lever arm 21. The other end of 'the lever arm 21 'is pivoted as at 22 to the-lever arm 13 between 30 its pivot or fulcru-m 12 Vand its free or trigger end 14. A coiled spring 23 connects the lower end of disk 16 with the lever arm 21 at a point between its connection -22 With the lever arm 12 and its hooked end 20. 85

The operation of the parts of the device Ias hereinabove described is as follows: In normal or in operative position as illustrated in Figs. 1 and 3, the coiled spring 23 vertical or upright position Vand also turns the disk 16 so that its cam face 18 abuts at the base against the stop pin 24 and the toothed end 20 of the lever arm 21 engages the 4notch 19 of the disk 16. `A rrovement backward of the rtrigger 14 serves lirst to turn the disk 16 `0n its pivot against the tension of spring'23-untiltheparts assume the position shown in Fig.2. A further pull upon trigger 14 will then result in disconnecting the arm 21 from the notch of the disk 16 and said disk is then permitted' -to return to its normalposition, the Fspring 23 causing the disk to turn rapidly and with considerable force.` rllhe disk 16 is made of steel or other hard material.

Referring now to Fig. 6 the construction and arrangement of the sparking material pencil or rod '24 of sparking material, either 110 flint or such substitutes'as arel wellknown inthe art, and between the rear end of the pencil 24 and the interior of the cap 10-'itting on said `nipple 8 is arranged the spring adapted to force said pencil 24 inward toward and down upon the toothed periphery 17 of the disk 16. The cap 10 serves as a means for adjusting the pencil 24 toward the disk 16 and sei ves as a means, therefore, for taking up the wear upon the end of said pencil as it is abraded by the teeth 'of said disk f'16. The spring 25 permits the pencil 24. to retract in the nipple 8 when the disk 16 is turned in one direction bythe lever arm 21 jand trigger 14 but forces the pencil firmly in the path of the ratchet teeth 17 when the disk 1,6- is rapidly turned bythe spring 23.

Continuing now the operation of the device, as the toothed disk 16 is turned under the action of its spring 23, the ratchet teeth 17 on said disk strike rapidly upbn ,the pencil 24 of sparking material and 4dig` out or abrade from the face of said pencil 24 a succession ofl minute particles which readily incandesce by reason of their separation from the pencil under a succession of rapid blows. These sparks as shown by dotted lines, Fig. 3, are guided through the cut away portion 11 to the gas jet or similar object to belighted. "hile the disk 1G is turning rapidly under the influence of its spring 23, said spring 23 also draws the lever arm 21 upward with its toothed end 20 riding upon the cam face of disk 16 until the toothed end 20 again rests in the notch on the periphery of said disk.

I claim:

, 1. In a device of the character described,l a handle, a trigger pivoted to said handle and projecting therefrom, a striking meme ber pivoted to said handle and having a ,series of teeth on one part thereof and a notch in another part thereof, a spring holding said member in a normal position, and an arm pivoted to said trigger and having a tooth adapted to engage said notch and move said member against the action of said spring and to release itself from said A notch, in combination with a `sparkingniemadapted to engage said notch when said member and said arm are in normal position, and a Sprmg'havmg one of its ends connected to said member and yieldingly holding it in'its normal position and the other of its ends connected to said arm and Copies of this patent may be obtainedvfor yieldingly holding it in its normal position, in combination with a sparking member adjacent to and in contact with the toothed part of said .striking member.

3. In a device' of the character described, a handle, a trigger pivoted to said handle and projecting therefrom, a. striking member pivoted to said handle and having a series of teeth on one part thereof and a notch in another part thereof, an arm connected to said triggerjand having a tooth adapted to engage said ntch when said dmember and said arm are in normal 4position, and a spring having one of its ends connected to said' member and yieldingly holding it in its normal position and the other of its ends connected to said arm 'and yieldingly holding it in its normal position, said member having a cam surface leading to said notch and said spring drawing said arm toward said surface, in combination with a sparking member adjacent to and in cont-act withthe toothed part of said striking member.

4. In a device of the character described, a handle, a trigger having its lower end pivoted to said handle, an arm having its rearward end pivoted t'o said trigger' above the trigger pivot, said arm having a tooth on its forward end, a striking member pivoted to said handle below the forward en'd of said arm and having a notch in the uppery portion thereof adapted to be engaged by said tooth, said member having -a series of teeth on the forward face thereof, and a coiled spring having its forward end connected to said member below its pivot and its 4rearward end connected to said arm, in combination with a sparking member adjacent to and in contact with the toothed part of said striking member.

In a device of the character described, a handle, a trigger pivoted in said handle between its ends, a lever arm having a toothed end and pivoted to said trigger, a disle having on one portion of its periphery a sries of ratchet teeth, and on the other portion of its periphery a notch? andta nam surface, the toothed end of said loyer arm adapted to ride upon the cam surface of the disk and to enter the notch and a coiled spring connecting t-he lower e'd o f said disk ywith said lever arm, in combination with a sparking member carried in said handle adjacent to and in contact with the toothed periphery of the disk.

i In testimony whereof I affix my signature in presence of` two witnesses.
